Abstract

The utility model relates to an alarming cushion for urine which can send out a remote alarm signal after a diaper is wetted by the urine. The alarming cushion for urine mainly comprises a sensing electrode, an electronic switch, a three-point oscillator and a transmitting antenna, wherein, the sensing electrode comprises pervious woven cushion and conducting strips fixed to the cushion which are connected by metal snap fasteners and the electronic switch. So long as the woven cushion is wetted by the urine, the electronic switch is turned on, and then through the oscillator the antenna sends out an alarm signal received by a receiver which can send out alarm sound.

Description

Remote-controlled alarm wetness for diaper

This utility model relates to a kind of call alerts device, particularly a kind ofly is used for infant can send the tele-alarm signal after wet because of big or small potbellied the pad of reporting.

Existing just wet alarm device mainly is made up of acoustic alarm integrated package, sensing electrode and sounding component.But its sensing electrode is to be connected on the main body of alarm device, need during use sensing electrode is clipped in the diaper, and the sensing electrode metals that adopt is made or humidity sensing element more, and is not too convenient when therefore using.Transducing part as the disclosed automatic warning baby bunting of Chinese patent CN89200115 adopts aluminum strip; All must be placed on two sensing electrodes diaper on when the disclosed baby's urinating alarm of Chinese patent CN89212788 uses at every turn and clip, they can not be contacted each other, thereby the sense of inconvenience be arranged for the people more.Need be placed on human external as sounding component, chimes of doom is just more clear, particularly night the adult sleeping after clearly chimes of doom seem even more important, but the existing just sounding component of wet alarm all is to draw by lead, gives the sense of burdensome and inconvenience again.

It is little, easy to use that the purpose of this utility model provides a kind of volume, and can send the just wet pad of reporting of tele-alarm signal.

The solution that realizes this utility model purpose is: the remote control that is provided is just wet to report to fill up and is comprised a sensing electrode, this sensing electrode is by the nonwoven pad of porous and be fixed on the conduction of two on this nonwoven pad cloth and form, the conduction cloth links to each other with the input of electrical switch by the metal sublayer box, the outfan of electrical switch is connected to a bikini oscillator, and the outfan of this agitator is connected to transmitting antenna.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is the circuit theory diagrams of an example of this utility model.

Fig. 2 is the circuit theory diagrams of another example of this utility model.

Fig. 3 is the receiver principle figure that is used with this utility model.

Fig. 4 is overall structure figure of the present utility model.

Fig. 5 is the cutaway view at Fig. 4 A-A place.

As shown in Figure 1: after nonwoven pad 1 is wet by urine, two on it conduction cloths 11 are connected, input as the integrated package 2 of electrical switch is low resistance state, its outfan conducting, the bikini oscillator of being made up of audion 31, inductance 32,

electric capacity

33,34,35 and

resistance

36,37 3 produces vibration, and its signal is launched by antenna 4.This alarm signal can be sent chimes of doom after being received by receiver.The schematic diagram of receiver is as shown in Figure 3: the signal that antenna 5 receives is by after superregenerative detector 6 detections, and input acoustic alarm CMOS integrated circuit 7 amplifies the back ceramic generating device 9 of drive through audion 8 and sends chimes of doom.

If under the situation that collective's occasions such as hospital or nursing room are used, can adopt the coded signal emission, as shown in Figure 2: promptly between as the integrated package 2 of electrical switch and bikini oscillator 3, be connected to an encoder 10, so that discern the just wet diaper of which baby.Encoder 10 can adopt cmos circuit KD-12D type multichannel remote-control coder; This encoder just can be combined into different codings easily as long as different input and output pins is joined.Certainly, also a decoder should be set correspondingly in the receiver.

In addition, also can be between two conduction cloths 11 a critesistor 12 and critesistor 13 in parallel with positive temperature characterisitic with negative temperature characteristic, in case the baby is heated or suffers from cold.Kicked open and ambient temperature when low when wrapping up in, as when being lower than 25 ℃, resistance 12 is low resistance state; When wrapping up in lid very little and ambient temperature is too high, as when being higher than 35 ℃, resistance 13 is low resistance state, and alarm signal is promptly sent in electrical switch 2 conductings.Resistance 14 is used for the attemperation scope.

Overall structure of the present utility model such as Fig. 4, shown in Figure 5: the electronic component in the foregoing circuit is contained in the capsule 17, the box outer casing bottom embeds two metal ZIKOU 16, this metal ZIKOU is serially connected in the foregoing circuit with on-off mode, nonwoven pad 1 adopts lining silk, be sewed with two conduction cloths 11 on it abreast, the end of nonwoven pad 1 is fixed with two metal boxes 15, and they are connected with conduction cloth 11 respectively.

This utility model makes sounding component separate with the baby owing to adopted remote control mode, solved the problem that in the past will draw sounding component with lead, and volume can dwindle more also.In addition, owing to adopt double buckle to connect sensing electrode, conduct electricity the nonwoven pad of cloth soft and can arbitrarily fold and have, so clean, use is all very convenient.

Claims

1, the just wet pad of reporting of a kind of distance type, comprise a sensing electrode, it is characterized in that said sensing electrode is by the nonwoven pad 1 of porous be fixed on the conduction of two on this nonwoven pad cloth 11 and form, conduction cloth 11 links to each other with the input of electrical switch 2 by metal sublayer box 15,16, the outfan of electrical switch 2 is connected to a bikini oscillator 3, and the outfan of this agitator 3 is connected to transmitting antenna 4.
